To all 'whoml 'itmay concern:

of Cliftonv Springs,fin the county of Ontario and State of New York, have invented a neuT and useful Improvementin Sanitary Milk-Cans, which improvement is fully set forth in the following specification and shown inthe accompanying drawings.

vThis invention relates to certain new andy useful improvements in receptacles designed prima-rily-for use as milk cans, but, as is evident, adaptedfor other purposes.

' It has for its objects among others to provide what I term a sanitary milk can, so constructed that the entire interior surface of the can' below the-rest for the cover is practically continuous and smooth, being free of creases, grooves or open joints, thus rendering it capableof being conveniently, readily and thoroughly washed and avoiding places which Wouldn-tend -to hold littleremnants of milk which would sour therein.

It has for a further object to Yrov'ide. a siml' `ple and efficient protecting jac, et which will serve not only t`o resist 'transmission' of `external heat through the walls of the can`\ to.

its contents, but which -will also-strengthen the can and enable it tobetter withstand the rough handling which it is sure to get while in* transmission in the baggage cars o'n the railroad and at other tim I form the upper end ofthe 'can in'a.-novel manner for coperation with the cover'so' as to prevent upward 4slo'pping of the milk from passing outward around the cover, so that should the milk xsplash upward, the comparatively smaller diameter of the body at the ltop will direct the splashes of the milk past the joint between the cover and the contiguous .portion of the body and into the hollow member of. the cover, thus breaking the force of thel splashes so thatnone of the liquid can pass outward between the cover and the conti ous surface of the cylindrical portion of tie upper end of the can.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly j pointed out in the` appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with, the numerals of reference marked thereon, form a part of this specificatiom and in which- Figure 1 is a sidleelevaton-of the can with parts broken away and other parts incentral vertical section.. Fig. 2, drawn to alargar scale, shows the'upper portions of thecanf with a slight modification in the foi'm of the upper end f' the main body portion. gFig. 3 is a plan df the can viewed from above, a

part 'of the coverbeing broken away'. Fig. 1 4 is'a side elevation of the cover detached,

partsbeingbroken away and shownin diametrical section on-the dotted line a in Fig. 3. Fig. 5 shows more 'fully the construction -atthe bottom pf the can, parts-being broken away and iiivertical axial section. Fig. 6 is a detail side view of an embodiment of the invention in .which the handles are secured toa band 'which tits snugly the body of the' can. 'l f Like numerals offreference indicate like l parts throughout the several views.

Referr to thedrawings, 1 designates the'bottom of theean which is.shown' as saucer-shaped having at its upper edge an annular outwardly extending flange 12, f'as seen clearly in Figs. 1 and 5. It is formed preferably at 'its' edge S'practically on the are of a. circle,l meeting the lower contiguous' portion tof thebody 5 oft-he canas in a continuousline, seen best'. in Fig. 5, so there. is left n roughness of the inner surface where thegsaid-bottom and the lower end of the body of the can meet. The joint at this point may be closed by solder or otherlj wise so that n0 milk or other fluid can enter The flange 2 ofthe bottom 1 extends over and rests uponthe upper edge of the bottom ring or foot 6, which latter element is eommon in cans of this general character, and the body portion 5 of theean has a circular shoulder or extension outward, as shown at- 7, see particularly Fig. 5, which rests upon the flange 2 of said bottom, and the lower end of the body p ion is then extended to form an annular rtion or skirt 8, which extends downward* over the outer edge of vthe flange 2 and snugly embraces the bottom milk. -This is preferably arranged asv seen is-l'held a ainst'se Jaration so as to Y g l avoid opening of the joint "at this point.

In constructing the can, l provide a jacket' which-serves the double 'function of protect ing the -body of the can proper during rough.

handling While in transmission o rin use and at thesame time resist the transmission of external heat through the walls of the can to the milk or other-contents. 'InFig. 1v I'have shown one forinof protecting-jacket, as at 10. This extends fromV A"near the bottoni of the can to a point' at or about the niidheight thereof, its upper 'end being secured to the body 5 by a ring of solder or thev like, as at' 11. This jacket isl also conical, but of a slightly less sharp in. .clinationthanthe body 5, it touching the body at its upper end but leaving a gradually increasing space 12'which is of coin.- ,120.

.paratively considerable width at its lower end, as Aseenrclearly inF-ig. 1. The lowerend of this jacket extends downward and beyond, the top edgeof the skirt Sand is there firmly secured in 'any suitable manner, .as seen at 13, as by solder or otherwise. lVitliiu the; conical space 12, just referred to, I

I place a sheet or sheets or layer or layers of asbestos 14, or-some other suitable substance that will resist the transmission of external heat throughthe walls of the can to the Vin '1, so as to leave an air space upon both'sides thereof to increase the heat resisting qualities.- 'This jacket maybe. corrugated, as at 15 in Fig.: 1. AThese corrugations, while not necessarily always present, serve to strengthen 'the jacket, as well'ias to -materia lly protect the saine during the rough handling that such a can is 4liable to receive 1n use.

' In Fig. (i Iliave shown another' forni of jacket as at 16. This is'comparatively short, the upper e'nd'being secured to the body 5 by a ring of solder or the like, as seen at 17, and thelower end being likewise secured' to the body by a ring of solder or the like,

` as seen at 18. If desired this form of jacket also may be corrugated, as seen at 19; Also the' corrugations may extend horizontally or -verticall'i 'or at an inclination, or both, as

may be' ound most expedient. ln this form the jacket ftssnugly to the body of the can and the interposed heat resisting material is notemployed.. I

Handles 20 are employed, as seen in the diierent views, said handles being secured to thejacket's. of whichever form may be i. employed, the handles' beingv disposed at a point. substantially near the niidheight of .thecan forconvenience in handling. These l handles/arev riveted to thejacket without riveting through the body of the can. The jackets may be of any suitable height, as

may be required toprotect the can a ainst.

becoming indentedjor jammed, as its ifer- .ent uses may require'. By this means, rivet heads on the inside'of the vessel or can .are

avoided.

-A can constructed u sabove described has the following advantages. It can be easily 7|` cleaned and kept in a samitary'mindition4 as. it is Iconst iuctlil so as to avoid allturns, bend,l or s .iarp 4' 'ingles on the-inside and all, of th'e in11eisuri` ,ce isfully exposed to view,

while the body .is of such a shape or 'forni/l5 that-'che sides of the 'same will not come in Contact 'with the-sides of similar vessels 1n Ahandlingl or shipping and, vby this mcarl,

the .canl is not hable to become jammed.' QI' dented and thus uneven surfaces on the i11- sidc are prevented, which also adds t0'- the ease ot cleansing-the interior ot the can'. 21designates the cover.

is av cylindrical band :1t-the upper. end

of the body portion.-4 This ring or band is maderigid with' vthe body -5 bya tapered ring'fof 'solder or the like 23,115 seen-in said Fig. 1. This-band 1s formed with a circularhorizontal crease 'or outwardly extendmgre- 'cess 24, as seen in Fig. 1, into whichthe-- o uter edge of the outwardly lextending flange 25 atvthc upper end 'of the bcdyprd jects and into which' it is rigidly soldered,

leavingr a I horizontal flange,z orcircular shoulder 2 6 for receiving thebottomedge of .the cover, as is lclearly'shown in Fig;1.

The cover 21'is constructed of parts-as shown in liigs. 1 and 4 These comprise the -two hollow. or saucerlshaped members 27 and 28ndisposed -in oppos1te"relation that is turnedbottointo bottom, as seen clearly i'n-said views, and the lower member-being cylindrical. 'Around the lower'-cy'flindrical part 28'is placed-a second cylindrical part 29, which la tter .is designed to telescope direetly within the' band '22 to -tightlyclose the can, as seen inlFg. 1. Atits'upper end,

the cylindrical part 29 is turned outwardly: to form an outwardly: projecting horizontal {iange 30, around the outery edge of which in Fig. y1. The cover is forinedwithan-up-- wardly projecting handle 33,.'as' shown in yFigs. 1, 2, 3 and 4, which is formed Iwith. a

downwardly projectngfhorizonthl stitenlng rib 34 as seen best in Figs. 1 and 4.

The upper -edge of the band 2,2 is rolledl .Y l

in FigsL `1, 2 and 4.

outward around a wire 35, as shown clearly In the forxnshow'n' Fig.' the-upper-v l lend of the body portion 5, nstea'dof beingv turnedl outwardv` to" form the horizontal.. Vflange -described in connection with-Figs. 1

CII

and 4t, is coiled around a Wire 36, as shown,

the coil being s:.ftward. to meet the inner surface of the cylindrical band :22. This forms a ring or internal recess 37 for the lower edge of the Cover, answering the same purpose as the shoulder 26 in the form shown in Fig. l. In this form, the hand '22 is plain and not provided with a groove or recess, as is the form shown in Fig. l at 2l. The result is substantially the Same. The object of this shoulder or recess is'to pre Ventthe upward slopping of milk from passing outward around the cover, the internal diameter of the lower portion of the cover being greater than the diameter of the mouth of the body portion 5, as shown clearly in Fig. l, so that if the Tnilk splashes upward, the comparatively smaller diameter .of the body at the top will direct the splashes of milk past the joint between the @over and the contiguous -;h ulder, 2G or 37, as the case may be, and into the hollow ofthe lower member 28 of the cover. p This breaks the foree of the splashes and none of the milk can pass upward and outward between the cover and the contiguous surface of the cylindrical band '22.

Modifications in details may be resorted to without departing from the spirit of the invention or sacrificing any of ite advantages.

o1 the body,' the inner walls of said bandbeL ing parallel, and a closure having a cylindrical portion tightly fitting the inner vwall of the band from the upper edge of the lat*- ter to the upper edge ot' the can body, the

lowermost portion of the cover-resting upon the upper edge of the can body, and the Cover being provided with a downwardly opening* chamber entirely above the eone shaped body.

In witness whereof, I have hereunto seb my hand this 17th day 0f February, 1910,

in the presence of ,two subscribing witnesses.
